Ossification
formation of bone from fibrous tissue, continues until maturity.
cortical bone
hard, dense, strong bone that forms the outer layer of bone; also called compact bone
cancellous bone
lighter, less strong bone that is found in the ends and inner portions of long bones; also called spongy bone
epiphysis
wide end of long bone which is covered with articular cartilage and composed of cancellous bone
diaphysis
Shaft or middle region of long bone that is composed mainly of compact bone
proximal epiphysis
the end of the bone that is located nearest to the midline of the body
distal epiphysis
the end of the bone that is located farthest away from the midline
physis
cartilage segment of long bone that involves growth of the bone: also called growth plate or epiphyseal cartilage
metaphysis
flared portion of a long bone shaft, adjacent to the physis (growth plate); in adult animals, it is considered part of the epiphysis
periosteum
the tough, fibrous tissue that forms the outermost covering of bone
endosteum
tough fibrous tissue that form the lining of the medullary cavity
long bone
bones consisting of a shaft, two ends, and a marrow cavity (i.e., femur)
short bones
cube shaped bones with no marrow cavity (i.e. carpals)
flat bones
thin flat bones, usually curved (i.e. ribs, shoulder blades, pelvis, and skull)
pneumatic bones
sinus containing bones (i.e., frontal bones of skull)
irregular bones
unpaired bones (i.e., vertebrae and hip)
sesamoid bones
small round bones embedded in tendons (i.e., patella)
